In this simply beautiful VIS image, taken by the NASA - Mars Odyssey Orbiter on September, 27th, 2003, and during its 7.916th orbit around the Red Planet, we can see a small portion of the Region found at the start (---> beginning) of Morava Valles.


Morava Valles is a small Outflow Channel located in the Martian Sub-Region known as Margaritifer Sinus (which is part of Margaritifer Terra). Several of the Interior Channels of Morava Valles emanate from a localized Sub-Region (seen here) made of Terrain that is litterally "caving (sinking) in" (---> meaning that this Terrain is characterized by the occurrence of the phenomenon known as “Subsidence" - or even "Collapse"). This Sub-Region also comprises jumbled Blocks of Flat-Topped Hills - also very well visible here, in the lower portion of the image - which, as you know, are commonly known as Chaotic Terrains.

This image (which is an Original Mars Odyssey Orbiter falsely colored and Map-Projected frame published on the NASA - Planetary Photojournal with the ID n. PIA 19491) has been additionally processed, magnified to aid the visibility of the details, contrast enhanced and sharpened, Gamma corrected and then re-colorized in Absolute Natural Colors (such as the colors that a normal human eye would actually perceive if someone were onboard the NASA - Mars Odyssey Orbiter and then looked down, towards the Surface of Mars), by using an original technique created - and, in time, dramatically improved - by the Lunar Explorer Italia Team.
